The pro drivers running V2's i.e. Rhienhard is using the new endbell config. I believe this was done just for that reason. He is also using two fans one on the endbell and one on the esc. Many of the pro drivers were having the solder melt because they push the motors to the extreme. This is the first I heard of that it is only happening with the IB's and not the GP's. There might be some truth to this only because more amps create more heat, so these high output batteries could be one of the factors in this occurance.!!! I don't think it's poor soldering or over timed motors.
Just the nature of the beast!
